“…158 Specifically, the interfaces between magnetite and three popular BG systems, 80SiO 2 -15CaO-5P 2 O 5 (80S), 58SiO 2 -36CaO-6P 2 O 5 (58S), and 35SiO 2 -50CaO-7P 2 O 5 -7MgO-1CaF 2 (35SM) in mol.%, were investigated. 159 This study reveals that Fe moves much faster to the glass phase than Si transfers to the ferrite phase. Moreover, the diffusion rate of the Fe to glass phase is not the same in all the samples.…”

Hyperthermia (HT) is a rapid cancer therapy inducing cellular apoptosis by increasing the local temperature of cancerous tissues between 40 and 44°C. 1 The tumors are highly susceptible to this thermal range at which cancerous cells are destroyed, while the normal cells undergo no significant damaging effects. HT is induced by using magnetic materials under an alternating magnetic field (AMF). Benefitting from some favorable characteristics of magnetic nanomaterials (MNPs), magnetic HT has drawn enormous attention and reduced the adverse side effects related to conventional treatments of several tumors such as prostate, glioblastoma, and metastatic bone cancer. 1 This method is usually combined with other therapeutic approaches like chemotherapy (drug delivery), photothermal therapy, gene therapy, immunotherapy, and high-intensity focused ultrasound, which is critically discussed in this paper. 1 The exact process of HT is not yet fully understood since a variety of biological effects can simultaneously occur like heat-induced alteration of cells signaling pathways, DNA, and RNA alterations; expressions of heat-shock proteins; and many other biochemical changes, as well as the direct cytotoxic effect of heat. 2,3 Still, there is a theory which has been mostly accepted by scientists that the impaired vascularization of tumors, together with heat, leads to the lack of oxygen in the tumor environment. As a result, malignant cells escalate their anaerobic metabolism

“…The O 1s XPS spectra may be seen around 532.3 eV as mentioned in Table 1. Although it is challenging to obtain O 1s data because of overlapping oxide peaks and the possibility that the material surface has been hydroxylated or carbonated, the peak at about 532.3 eV is frequently attributed to the oxygen in a silica environment that is typical of silica glasses [25] . The iron band at 710.1 eV in the BG sample indicates that magnetite is successfully templated on BG particles.…”

Multiple biological advances have made use of bioactive glass (BG) nanoparticles (NPs) in regenerative medicine, bone and tooth repair, drug and gene transfer, cancer treatment, and cosmetics. Normal biocompatible coatings alongside hydrocarbons, polymers, and silica significantly affect fundamental attributes of NPs. In this study, we synthesized a novel mesoporous BG NPs with magnetite core shell (AMAG_BG) using L‐arginine as a template processing magnetic hyperthermia (MH). BG network coverage on magnetite (AMAG) NPs were orchestrated first time by bio‐inspired synthesis in watery dissolvable. AMAG and AMAG_BG NPs were characterized by utilizing FE‐SEM, HR‐TEM, and BET analysis. The elemental composition of L‐arginine templated magnetite (AMAG) and AMAG_BG NPs was also determined by XPS and EDX analysis. Characteristics of AMAG_BG were contrasted with bare AMAG NPs in morphology, particle size, porosity, and composition. The fabricated BG NPs′ in‐vitro bioactivity and heat studies were successfully monitored after interaction with simulated bodily fluid (SBF). Magnetic studies and in‐vitro heat studies together demonstrated the behavior of BG NPs towards MH treatment of cancerous cells. Cytotoxicity tests on AMAG_BG NPs using U2OS and human blood cells with appropriate control experiments revealed biocompatibility. The study represents magnetic and thermal property‐dependent sustainable synthetic process of AMAG BG NPs for cancer treatment.
